If you are thinking about fitting your own hood then you must get this dvd.It takes you through every stage of the removal and replacement process with excellent close ups showing every detail. Whilst it features a Mk1 hood, I used it as a guide to fitting a Mk 2 hood and it was absolutely invaluable. The two hoods are pretty much the same and differences between Mk1 and Mk2 are slight and obvious when you are doing the job.
Can't speak highly enough of this product!!
